  1. CS 575Lecture 3Spring 2012 K.V. Bapa Rao CSULA

  2. Overview • Review Licklider’s papers from lect 2 • View Berners-Lee Web development video • Follow up needfinding exercise

  3. Review of last week’s needfinding exercise • post-earthquake scenario • 5 families on a block • people know their neighbors but not much about anyone else • sporadic phone & internet communication (phone better than internet) • needs • Injury • food • damage to home • missing relatives / pets • Getting help to come to you • Procurement • Barter • Keeping track of balance • Money transfer • different resources • engineering skills • community resources information • money • food • external connectivity • family members outside disaster zone

  4. Summary of Notes • Adding tradeoffs / detail to requirements (when does mom need to know?) • Trade time for [what?] • Change • New info • Have an evolvable plan • If X happens within time Y, we can do Z1, Z2, … • Explore possible steps • Develop more information and expand possibilities • Refine choices: trade how much food? • Prioritize • Meet immediate & pressing needs • Detail plan • Cover self as well as others • Execute? • Evaluate / correct? • Develop more resources • Think of unusual resources (e.g., train station)

  5. Self-Evaluation

  6. Quality of Observations • Self observation & notes • How many others did you observe? • What questions did you have in mind when you observed?

  7. Breakdowns & Opportunities • Where are the pain points? Badness of experience? • Breakdowns • Unmet needs • Wasted time • Innovations & work arounds … • Come up with 3-5

  8. Ideas for user needs • What needs would you meet in an app? • List as many as you can (10? 15?)

  9. Inspirations • See people doing something, have an “aha!” moment • X would be a really great new product / service /app • This is how I would go about making X happen • I watched people doing Y and it made me think of X

  10. Use Cases (develop the ideas) • 1 for each group

  11. For next week (homework) • Develop detailed scenario / storyboard for your app • See Assignment 3 under Klemmer’s Stanford course for a guide

  12. Keep in mind the real-life constraints • State your assumptions • Phones working most of the time with some delay • It takes average of 3 hrs before receiving a response to an internet query
